So now I'm thinking it could be better to simply take an analog signal from the motherboard into some el cheapo surround system like one of the 5.1's from Logitech.
Will this work ok for dts signals? I assume this way all the DA conversion occurs in the computer and I should get nice 5.1 from all sources.. am I right? Seems like a nice cheap solution rather than going to the expense of buying a new amp.
Appreciate anyone's thoughts on this.
